Have you done any diag and repairs yet?

I have the diag steps for these codes, can you do those or are you looking for a best guess on what is wrong?

Customer: replied 1 year ago.
Just wanting to know what all is wrong. Bad sensors, bad wiring, bad ecm etc. I'm fairly handy with vehicles but would like some direction before I start ripping and tearing.

Sure I can help. Below are the diag steps for these codes.

Do you understand those tests? C1238 means the EBCM is disabling because it detects a rotor temp over 700 degrees from excessive braking or wheel spin during a traction control event.
